Study Finds More of Earth Is Hotter and Says Global Warming Is at Work

Over the last few summers, more and more of the Earth’s land surface has been covered by extreme heat.  In 1980, this number was only 1 percent as opposed to as high as 13 percent over the past few years.  Themain cause behind this extreme heat, according to scientists was caused by the “human release of greenhouse gases.”  Dr. James E. Hansen, a prominent NASA climate scientist claims that “the change (in heat) is too large to be natural.”  His opinion, however, has been controversial among his peers.  He has even been accused of manipulating temperature records to make global warming seem like even more of a threat than it already is, even though there is no proof of him doing this.  As long has the idea global warming has been around, it has been believed by scientists that it was the result of greenhouse gases released by humans from burning fossil fuels.   They have said that these emissions have made weather extremes such as heat waves, heavy rains, and snowstorms, more likely.  Dr. Hansen’s recent paper, “Perception of Climate Change” compares climate from 1951 to 1980 to the climate from 1981 to 2011 during June, July, and August.  From 1951 to 1980, Dr. Hanson and his coauthors found that “only .2 percent of the land surface was subjected to extreme summer heat” as opposed to “4 to 13 percent” from 2006 to 2011.  Unfortunately, Dr. Hansen believes that things are only going to get worse.  Dr. Hansen and his team came to the conclusion that recent heat waves and droughts were caused directly by climate change.  Although Dr. Hansen’s research has been viewed as more of a perception than an actual study, he and his team should be taken seriously.  Climate change is an issue that has a major affect on our world.  We must try to do everything we can to fix this  serious problem.
